In the moments before NASA's DART spacecraft slammed into the asteroid Dimorphos in a landmark planetary defense test in 2022, it took high-resolution images of this small celestial object and its ...
Near-Earth comets (NECs) are objects in a near-Earth orbit with a tail or coma made up of dust, gas or ionized particles emitted by a solid nucleus. Comet nuclei are typically less dense than asteroids but they pass Earth at higher relative speeds, thus the impact energy of a comet nucleus is slightly larger than that of a similar-sized ...
2024 BX 1 is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX 1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit. The bolide was studied in June 2024. It had a steep entry of 75.6° and an entry speed of 15.20 km/s.
2023 BU is a near-Earth object that passed 9,967 ± 1 km (6,193.21 ± 0.62 mi) from the centerpoint of Earth around 27 January 2023 00:29 UT. [3] Since Earth's radius is about 6,378 km (3,963 mi), it was expected to pass approximately 3,589 ± 1 km (2,230.10 ± 0.62 mi) from the surface of Earth over the southern tip of South America. [7]
In addition, it discovered 416 new objects and about a quarter of those were near-Earth objects classification. [60] As of July 2024, WISE / NEOWISE statistics lists a total of 399 near-Earth objects (NEOs), including 2016 WF 9 and C/2016 U 1, discovered by the spacecraft: [34] 365 NEAs (subset of NEOs) 66 PHAs (subset of NEAs) 34 comets
A large chunk of space debris that was discovered last month on a mountain trail in North Carolina came from a SpaceX capsule that had journeyed to the International Space Station, NASA has confirmed.
Lowell Observatory Near-Earth-Object Search (LONEOS) was a project designed to discover asteroids and comets that orbit near the Earth. The project, funded by NASA, was directed by astronomer Ted Bowell of Lowell Observatory in Flagstaff, Arizona. The LONEOS project began in 1993 and ran until the end of February 2008.
NASA has documented the diverse debris scattered by the 2021 landing of its high-tech Perseverance rover, including a strange-looking ball of tangled, "spaghetti"-like material, which the space ...
